Tomato Genetics

The lessons learned about tomatoes never seem to end. For example, just the other day POD learned that some heirlooms have a wilty gene. Who knew? Evidently, this simply means you need to water them more frequently than their brethren who lack said gene — perhaps something container gardeners should seek to avoid. And, I see rumors of tomatoes — heirlooms — that are genetically resistant to fungus.

I really, really want these tomatoes.

Does anyone have a list of varietys that do not contain the wilty gene and do contain the two genes responsible for fostering an immunity against fungus?
